Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0029] Such as figure 1 and 2 As shown, the ventilator includes an air source 1, an air-oxygen mixer 2, a host 3, a humidifier 4, and an external pipeline 5. After the air source 1 passes through the air-oxygen mixer 2, under the control of the host 3, it passes through the The external pipeline 5 is supplied to the patient, and the gas in the external pipeline 5 is humidified through the humidifier 4 at the same time; wherein the external pipeline 5 is provided with a frequency regulating valve in the present invention, including a main body 6, so The main body 6 has a cylindrical cavity, and a valve body 7 is rotatably installed in the cylindrical cavity, and a servo motor 8 is arranged outs...

Abstract

The invention relates to the technical field of valves, in particular to a frequency adjusting valve for a respirator. The frequency adjusting valve comprises a main body, the main body is provided with a cylindrical cavity, and a valve body is rotationally mounted in the cylindrical cavity; a servo motor is arranged outside the main body and is used for driving the valve body to rotate; in the rotating process of the valve body, the flowing area of gas passing through the main body is changed reciprocatingly, so that under the condition that the flow of a gas source is certain, different positive pressure values of the respirator can be adjusted, and different respiratory frequencies can be obtained by adjusting the rotating speed of the servo motor. By means of the valve, the problem that the breathing frequency of the respirator for continuous positive pressure airway ventilation is difficult to control in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a frequency regulating valve for a ventilator. Background technique [0002] Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. [0003] Continuous positive airway pressure is a major ventilator mechanical ventilation mode, which refers to artificially adding a certain positive airway pressure to the patient during the entire breathing cycle under the condition of spontaneous breathing. The specific wor...
